Unit does not have Dosimeter
Fully Qualified, except
EMC waivers; this unit did not see CE01, CE03 testing (ref. RFA-PER-1,3); turn-on transient
Contamination Inspection at GSFC
Shock and Acoustics deferred to Orbiter level
Sub-assembly identification
Electronics Ass’y: sn 001
Analog PCB Ass’y: sn 005
Digital PCB Ass’y: sn 001F
Telescope Ass’y: sn 003
PCB Ass’y: sn 003
